Nicolay Burkhardt - Pov.
*Metalic sound*
The constant sound of a hammer hitting red-hot iron was the only thing that could be heard inside a closed room. Finally, after a few months, I was doing something that brought me great happiness, in front of me the master blacksmith was hitting the metal with all his strength, honestly, this took longer than I had originally thought.
Four months had already passed since the factories began their creation, something I have to admit is that it is seriously slow, that is, I already imagined something like that, but seeing it can be frustrating. The manufacturers were barely reaching 40% completion, I guess I'm used to the speed with which things were built in my past life, those big machines are very helpful.
Anyway, due to the delay, people seem desperate to get their hands on the sugar. Only the last week I found five spies from the other houses trying to figure out how to produce it, I don't care much about anyone other than myself knows the production process, adding to this that the workers will not have the exact knowledge, each one will be applying something different, they very well that regardless of the measures there are ways in which information can be filtered is inevitable.
At least of course someone can read or influence people's minds.
According to the description of the first gift God gave me, the evolved body can influence the mind. Both knowing people's thoughts and shaping people's thoughts, even though it is not so advanced as to call me a telepath, is enough to keep the things I want to keep secret.
That is why in these four months aside from kenjutsu training. I dedicated myself to training my mind, meditation is more effective than I originally thought the results were acceptable in brief occasions I can hear whispers, I still do not understand them, but with time I will be able to shape them. This ability will help me to keep secret the ways of creating my inventions, I know it is unethical, but we are in the medieval world, also it would not be extreme to just play with their feelings to make them so loyal to me that if I ordered it they would commit suicide without thinking.
More than that, your life and mind will remain the same.
That reminds me, it seems that the mother has meetings quite often with the ladies of other houses. That sincerely I miss a lot, especially because a mother does not have a very good relationship with them, it is more or less a battle of poisonous vipers, well, perhaps removing Lady Catharine Stark and the Lady of the Morndmet I met her and I liked her a lot of people believe that because they are of barbaric descent, women are like corpulent men with an excess of beauty, nothing is further from reality, she is very beautiful and it seems that she has a daughter just like her.
Man, this tournament will be full of all kinds of things.
Beautiful nobles and princesses, lovely ladies and queens, gold in abundance, epic battles, and the odd idiot trying to stand out to get the attention of women, to be honest, this is nothing new even in my previous world there were such guys. I do not know why, but it is as if a mechanism will be activated in men when they are doing some activity and a beautiful woman is watching, they turn on energy trying to do everything surprising to stand out. Unfortunately, it doesn't work for all of them and they end up making a monumental failure hahaha.
I never tried something like that, but it seems like I have a chance to try. After all, it will be the first time I see my fiancee, who according to my parents is the most beautiful woman in the kingdom they repeat it quite often when I ask if it is as they say then it will be the objective of many gentlemen trying to prove their worth or shit like that.
"Young sir?" Bernal the blacksmith's voice brought me back from the world of thoughts.
I looked at him with a raised eyebrow in curiosity "Yes?"
"The procedure to create the weapon is already in the first phase but .." He replied between cut and tried to say something but did not dare endorse to ask more.
I smiled "What is say it?"
"Well ... After applying hammering pressure, I don't understand the next step, the shape and structure don't seem to be possible to create."
Laughing slightly, I walked until I was in front of the workshop table holding a pen while I spoke, I said.
"The elaboration of a katana can take months of work. It starts with the construction of a special type of oven called" Tatara "or in your case a normal clay oven, where for 3 days and 3 nights it is introduced and burns charcoal together with ferrous sand. This complex procedure will cause the iron to combine with the carbon to form the steel and, besides, it favors the elimination of many of the impurities present in origin. Indeed, it is necessary to consider Remember that the mineral deposits and ferrous sand deposits that are available provide a metal of very limited quality. This makes it necessary to develop especially refined techniques to eliminate the many impurities present.
The core of the steel produced is called tamahagane, which means "jewel steel". It is a porous block of iron and carbon, which still contains many impurities. The remaining material, lower carbon steel, is often reused as a metal reserve for the softer parts of the blade, or the carbon content is modified by adding parts of tamahagane. Tamahagane, in turn, has to be broken up into pieces that, due to their color, are subdivided according to their carbon content. These fragments are then heated and hammered until they are transformed into very thin sheets whose characteristics, such as the carbon content or the presence of impurities, are easily recognizable.
The best sheets are selected to build the outer skin of the blade, the kawagane or steel-skin, and the steel-blade Hagane are superimposed, heated with white heat, and melted together by percussion.
The reheating and percussion procedure is repeated more times to flatten and lengthen the steel block, which by this method also loses a whole series of impurities. At this point, the bar is ready to be worked. It is heated once more and an incision is made in the middle that serves to fold the steel bar back on itself. Once this is done, the block is reheated and struck more times, until the two layers are completely fused, which are flattened until the material adopts the initial dimensions.
The procedure will be repeated 6 times, approximately. The result will have to be a steel bar made up of thousands of overlapping sheets. Indeed, every time the steel is folded, the number of layers is doubled. "As I spoke my hand never stopped, sketching each step perfectly illustrated.
The blacksmith was stunned along with the apprentices little was left before his jaw dropped. On the other hand, without stopping I continued.
"At this point, the bar is cut into 3 parts. To build a sword or katana you need 4, therefore, one of the parts must be obtained from another block. The 4 steel bars are superimposed, heated, and melted by percussion The material is folded back and welded at least 6 more times. Each time the material is heated, it loses carbon that burns in contact with oxygen. All this means that, as the process progresses, the steel loses carbon, but in a non-uniform way, which is why the block will be made up of thousands of steel sheets, and in each one of them the amount of carbon varies considerably.
The result of this procedure is a steel bar made up of thousands of superimposed layers in a thickness of a few millimeters, to the point that we speak of 'molecular' thickness in each layer. Depending on how the steel is riveted and bent, always in a single direction or different directions, a different pattern is obtained on the surface of the fairy steel. In this phase of the process, the blacksmith begins the elaboration of the shingle 'core steel', starting from steel with low carbon content. This is profiled and then folded and tapped about ten times to successively reduce the carbon content and remove impurities.
In the end, it is time to put it all together, the kawagane is folded into a U shape and the shingle bar is inserted inside. The block is heated and beaten until a complete fusion between the two layers is obtained. This phase is especially critical since a correct weld must be produced and the blows must not dislodge the two components kawagane on the outside and shingle on the inside. The result of this complicated process is a blade composed of an extremely hard coating, very suitable for being sharpened, and a core that, on the other hand, is very elastic and able to absorb shocks without breaking. "
I walked towards them.
"In this phase, the future blade is heated again with yellow heat and struck to outline it, it is given the final shape, and the 'nakago' tenon and the 'Kiseki' point are also molded.
Finally, the most critical moment of the forging of a sheet arrives, the quenching by immersing the red-hot sheet in water or oil in some cases. Quenching in water is very complicated and subjects the blade to a difficult test, the truth is that the sudden thermal change notably alters the molecular structure of the bar, also modifying its shape and the curvature of the blade itself and reveals possible construction defects. , such as cracks or fissures.
Carbon adds toughness to steel because its large molecules interfere with the layers of iron, preventing them from slipping. over the others. The tempering process is a process that amplifies this effect, since, when the steel is heated, the crystalline structure of the iron disintegrates and the iron atoms mix with those of carbon. If the steel is cooled slowly, the iron atoms rebuild their crystalline structure, pushing the carbon atoms to the margins. If, on the other hand, the cooling occurs rapidly, the carbon atoms remain enclosed in the crystalline structure of iron, altering it and making it irregular. This makes it much more difficult for the iron layers to slide between them and thus greatly increases the hardness of the steel.
Hypothetical new heating can destroy the temper. In any case, the blade would lose quality, since the original characteristics that the creator had conferred on it were irretrievably lost.
The sword, in this phase, undergoes a second preparatory tempering: the blade is heated differently depending on its parts, the blade and the lateral faces are heated more than the core and the back and it is immersed in water. Then comes the time to temper the edge and create structure, the sinuous line that separates the edge from the body of the katana, and that indicates the two zones of a different temper. "
Look at everyone in the place, they seemed lost. Bernal seemed to have found some God in me because of the way he looked at me, I was sure that at any moment he would kneel to ask me to accept him as a student, the truth is that I have no experience in the smithy, I only know so I could not teach.
I smiled stretching the design sheets "Here is explained everything I said in detail, as well as the drawing of the separate design of the katana, If everything goes well it only takes a few months."
Bernal accepted the drawing with trembling hands as he nodded with more force than necessary "Yes sir! I promise For my pride as a blacksmith that I will have your weapon ready!"
Asen ti "Perfect, then I'll let you work."
Before I asked to get away from the door I could hear the screams inside the workshop.
"Hey, Frederic ...."
".... What happens?."
"Did you get anything?."
".... No .... to be honest, I got lost after it started."
"So am I ... but I have the impression that everything you just said is more knowledge than people like us could ever understand."
"Yes ... as expected of the young lord, it seems the rumors are so well unfounded."
"Shit brats! What are you doing idly we have a commission from the young lord! Shake those lazy asses !."
"Yes sir!."
...
...
...
Chuckling I walked away from the place, technically they are right this is ancient knowledge. That it does not belong to me or at least not before now that none of this exists I will claim it as mine.
